IMPROVEMENT IN LAMP-EXTINGUISHERS.

TO ALL WHOM IT MAY OONCERN:

Be it known that I, MARK SAFFORD, of Boston, in the county of Suffolk,and State of Massachusetts, have invented anew and useful Improvement inLamp-Burners; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanyingdrawings, in which- Figures 1 and 2 are side elevations andFigure 3 a section of a lamp-burner containing my invention.

Figure 4 is a rear side elevation of the wick-tube with my inventionattached thereto.

The invention in question is an improvement in that classofiamp-burnerS-in which a cap or plate is employed for covering the topof the wick-tube and extinguishing the flame, as well as for the purposeof preventing waste of the contents ofthe lamp by evaporation, and theodor of them from escaping intoV the apartment.

The invention consists in applying the extinguisher to the burner insuch a manner that it shall be actuated by a cam applied to theWick-elevator shaft, so that the rotation of this shaft, in the act ofelevating the wick, when lighting the lamp, shall rst move theextinguisher from oi' the wick-tube, and then raise the wick above thetube the requisite distance, the extinguisher subsequently coming backto place upon the lowering of the wick within its tube.

In the above-mentioned drawings, a denotes the body of the burner, and bits wick-tube, c being its notched wick-elevating wheel, and d the wireor shaft carrying the wheel, the parts thus described constituting theordinary burner. The extinguisher is shown as composed of a iiat plate,e, having at top a lateral bend or lip, f, to shut over upon the top ofthe wick-tube when the flame is extinguished, the plate e beingsupported at bottom by a horizontal wire or rocker-shaft, g, extending"across, and supported by, the burner, and situated in a plane with, andparallel to, the shaft UZ. A tripper or finger, h, is aiiixed to theouter end of the shaft g, and lies against the periphery of a cam, z',secured to the wick-elevating shaft 0l between its milled head and theburnerthe arrangement ofthe nger k and, cam z' being such that, onrevolving the shaft cl, the cam will so aetuate thenger as to causeapartial revolution of the shaft g, and remove the extinguisher from offthe wiektube before the wick reaches the top of the same, theextinguisher being forced up to or towards the wiek-tube by the actionof a spring, j, suitably applied within the burnei, and bearing againstit. By turning the shaft d in one directiom'tbat is, to the right, theextinguisher will be removed from ofi" the wick-tube, andthe wickvsubsequently raised above the tube into a position to enable it t'o beiniiamed, it being understood that the length of the wick is to be rstso adjusted 'tha-t, when the tube is covered, the wick shall be somedistance below its top, in order to give time for the extinguisher to bemoved out of its path before it reaches that point. By reversing themovement of the shaft d the Wick will first be lowered into its tube,and the extinguisher afterwards forced over upon and cover the-tube,thus extinguishing the ame, and preventing escape of odor, or waste ofthe contents of the lamp, as well as doing away with the dangerous habitof blowing out the flame. The shape of the cam z' is shown in tig, 1 ofthe drawings as composed of the segment of a circle, a', and a flatsurface, b', the length of the portion a determining the length of timerequisite to detain the extinguisher from off the wick-tube, as thevextinguisher will be free to cover the tube when' the iiat surface 11of the cam and the finger i are in contact.

I claim so applying the extinguisher to the burner that its movementsshall be actuated by the wiekelevating shaft, and by the same act whichraises and lowers the Wick, substantially in manner and for the pui'-pose as described. A

I also claim the device for causing the above-described movement of theextinguisher, consisting of the finger z and cani 2', applied to theshafts g and d, the extinguisher being moved in one direction by thespring j, the whole being arranged and operating together in manner asabove set forth and explained.

MARK SAFFORD.
